CONFAST 1/4 in x 1 in Hammer Drive Nail Anchor - Permanent Hold

In this review the CONFAST 1/4 in x 1 in Hammer Drive Nail Anchor is evaluated for contractors and DIYers who need a simple, reliable permanent anchor for concrete, block, and brick. The bottom line: this box of 100 anchors is best for jobs that demand quick installation and strong hold because the anchor installs with a hammer drive and is designed to remain permanently fixed once set. The review focuses on real use, ease of installation, and the materials and hole-size guidance that determine consistent performance.

Key Features

• Versatile base compatibility: Designed for use in concrete, block, and brick so one fastener covers common masonry needs.
• Matched hole and anchor diameter: The 1/4 in anchor diameter equals the required hole diameter, which simplifies drill bit selection and reduces installation guesswork.
• Packaged quantity: Each box contains 100 pieces, which helps professionals and frequent users keep jobs moving without frequent reorders.
• Permanent fastening: Once installed with a hammer drill hole and driven in place, the fastener cannot be removed, delivering a secure long-term hold for fixtures.
• ZAMAC construction: Made from a zinc-aluminum alloy that provides consistent performance in dry environments where these anchors are intended to be used.

Who It's For

The CONFAST hammer drive anchor is aimed at contractors, tradespeople, and informed DIYers who need an economical, reliable solution for attaching metal cleats, wood plates, or light fixtures to masonry. The 100-piece box and straightforward 1/4 in hole requirement make it especially useful on jobs where multiple anchors are needed and speed matters.

Those who should look elsewhere include users needing removable anchors, anchors rated for wet or corrosive environments, or applications that require higher tensile loads than a standard hammer drive anchor is intended to carry. For those situations, consider specialized anchors rated for exposure or mechanical expansion anchors with removable capability.

Pros & Cons

Pros

Cons

• Permanent fastening means the anchor cannot be removed, limiting reuse or adjustments after installation.
• Designed for dry environments only; not specified for exterior or corrosive conditions without additional protection.
